Abstract: Objective To select and obtain relevant evidence at home and abroad for the transport of critically ill patients, and to summarize the best evidence. Methods British Journal of Medicine（BMJ）, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Joanna Briggs Institute (JBI) evidence-based Health Care Center Database, Cochrane library, EBM Guidelines, European Society of Intensive Care Medicine（ESICM）, National Integrated Cancer Network Scottish Intercollegiate Guideline (SIGN), CBM, PubMed, CNKI and Wanfang Database on Cancer were searched by computer from the inception to July 25 in 2019 for literatures including guidelines, systematic evaluation, best practice information books, evidence summaries and expert consensus. Two researchers evaluated independently the literatures and extracted the documents meeting the standards. Results Fifteen articles were included, including 5 guidelines, 5 systematic reviews, 2 evidence summaries, 2 expert consensus and recommendations, and 1 clinical decision support. The best evidence was summarized from the following seven aspects: transfer personnel qualification and training, transfer equipment, transfer plan, transfer communication, handover record, transfer management, and transport adverse events,the total articles of 59. Conclusion This study summarizes the best evidence for the in-hospital transport of critically ill patients. Medical personnel should apply evidence in combination with the specific conditions of their own hospitals and departments, and use evidence in a targeted manner. However, it is still necessary to apply updated evidence in clinic to reduce the incidence of adverse events in critically ill patients.
